Ubuntu 10.04 LTS / 10.10 / 11.04 : exim4 vulnerability (USN-1135-1)

High Nessus Plugin ID 55096


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that the Exim daemon did not correctly handle certain DKIM identities. A remote attacker could send specially crafted email to run arbitrary code as the Exim user.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected exim4-daemon-custom, exim4-daemon-heavy and / or exim4-daemon-light packages.
